Cisco Catalyst 9200L Factory Reset

[gpavledes]

Is there a way to factory reset the Catalyst 9200L switch back to the zero day setup? I am completely locked out and need to start over. Thank you.

Have a look at this link and see Leo's solution.

Thank you for the suggestion, however I was not able to get this to work:  "Once the System LED starts to flash, press the Mode button 3 times in quick succession." Would there be any other suggestions please?

Hello

console cable
terminal emulation software (putty)
attach console cable to switch console port,

1. power on switch
   keep pressing grey button until you have bypassed the bootloader
   switch:
   
   
2. type the following:
   switch:SWITCH_IGNORE_STARTUP_CFG=1
   switch:boot flash:packages.conf
   switch:boot
   
   switch will boot up:
   
   
3. switch::enable
   switch#:wr mem
   reload
   power cycle switch
   
   
4. power on switch again
   keep pressing grey button until you have bypassed the bootloader, then type the following:
   switch:SWITCH_IGNORE_STARTUP_CFG=0
   switch:boot flash:packages.conf
   switch:boot

done

Hi Paul. I noticed you mentioned to press the grey button initially until you bypass the boot loader. Considering 9200s have a different from other models in terms of resetting to factory, will pressing and holding this button work on the 9200s?

hi to all, in the second step, before SWITCH_IGNORE_STARTUP_CFG=1, we need to use step, like this:

step SWITCH_IGNORE_STARTUP_CFG=1

thank you so much! This was the only solution that worked for me after trying many others.

You could try to get in the ROMmon mode by holding the Mode button (idk how long, just hold it long enough)

And from there you could delete the running.configuration file from the flash:

delete flash:running.config ? I am not sure about the exact command anymore

then you can boot again with the "boot" command and login again to your switch.

From there you can factory reset your Switch if you want

Thank you for all the suggestions. I was able to use a usb2 cable and get in through Putty. From there I was able to complete the factory reset.
